प्रश्न
What is the effect on the fringe width if the distance between the slits is reduced keeping other parameters same?
Advertisements
उत्तर
As we know that the fringe width is given by
β = λD/d
Hence, if the distance between the slits is reduced then the width of the fringes increases. In that case, fewer nodal regions are produced on the screen and the fringes will become wider but less in number.
